Introducing Active Dry(TM) Anhydrous Solvents from Alfa Aesar
Ward Hill, MA - Alfa Aesar, a Johnson Matthey Company, is introducing a new line of anhydrous solvents featuring the new Active Dry(TM) alkali metal silica gel system (Na-SG-I), an efficient drying agent and impurity remover for solvents and anionic polymerization processes.
Commonly used drying agents require distillation to remove traces of the agent. Standard drying procedures are also a tedious limiting factor in both at laboratory and industrial production scale reactions.
Active Dry(TM) provides drying performance on par with other recognized methods with the added benefit of not requiring a post-drying and post-purifying workup. Each Active Dry(TM) solvent includes an Active Dry(TM) pouch immersed in the solvent to ensure dryness, and is sealed using Alfa Aesar's exclusive ChemSeal(TM) septum caps. The initial line of solvents includes benzene, heptane, hexane, pentane, tetrahydrofuran and toluene.
